Comparison of Methods for Determination of Fluoride Ion in Industrial Wastewater
The method of ion selective electrode for the determination of water fluoride(GB/T 7484-1987)and the method for the determination of low content fluoride(HJ 488-2009)were discussed.The method conditional test studies were carried out on the preparation work before measurement,linearity of the standard curve,detection lim-it,spike recovery,precision,accuracy,sample determination,and method comparison.The experiment shows that fluorine reagent spectrophotometry is suitable for the determination of clean water samples without interference,and it is cumbersome and time-consuming to operate;the ion selective electrode method has a wide range and accurate results,which can quickly guide the production is an economic and classic fluoride detection method.
